Network projectors: frequently asked questions

A network projector is a video projector that's connected to a wireless or wired local area network (LAN).

What sets the network projector apart from other presentation methods is that you can connect to, and operate the projector remotely over, a network connection. If your computer can connect to the projector, you can deliver a presentation from any location that has network access, whether it's your private office or a conference room where the projector is located. Those who want to view your presentation must be in the same room as the projector; they can't view the presentation over the network from a different location.

To start, connect to the projector by using one of the following methods:

Open the Connect to a Network Projector wizard by clicking the Start button . In the search box, type Connect to a Network Projector, and then, in the list of results, click Connect to a Network Projector.

After you find a network projector
in the wizard, click Connect.

Once you're connected, you can control your presentation in the Network Presentation dialog box by clicking Pause, Resume, or Disconnect.

If you know a projector's address, open the Connect to a Network Projector wizard, and then click Enter the projector address.

Each projector on the network is identified by a unique address. You can enter the address as a URL (a web address, such as http://server/projectors/projector_1) or as a UNC path (a path on a server, such as \\server\projectors\projector_1). Your system administrator might be able to give you the address of a specific projector.

The address is displayed on the projection screen when a presentation is not in progress. If you're using a security-enabled projector, the projector password is also displayed.

One or more network-related problems are preventing your computer from connecting to the projector. For example, a router or DNS server might be down.

A firewall could be blocking the outbound connection on the projecting machine.

One or more services required for network projection might have been turned off by Group Policy.

The projector is connected to a different network than your computer. You might need to ask your network administrator for permission to access the network that the projector is connected to.

The projector might not be configured to accept ad hoc network connections, even if the projector is connected to a wireless access point. You might need to ask your network administrator for credentials to connect to the network that the computer is connected to, or ask the network administrator to configure the projector to accept ad hoc network connections.

If you change how your desktop is displayed while your computer is connected to a network projector, the connection might disappear without warning. For example, this might happen if you change your desktop from Extend to any of the three other options (Computer only, Duplicate, or Projector only). If you lose your connection, try reconnecting to the network projector.

Network projectors are designed to transmit and display still images, such as photographs and Microsoft Office PowerPoint slides—not high-bandwidth transmissions, such as video streams. The projector can transmit video, but the playback quality is often poor.

Those who want to view your presentation must be in the same room as the projector; they can't view the presentation over the network from a different location.

Each projector on the network is identified by a unique address. You can enter the address as a Uniform Resource Locator (URL) (for example, http://server/projectors/projector_1) or as a UNC (Universal Naming Convention) path (for example, \\server\projectors\projector_1). Your system administrator may be able to provide you with the address of a specific projector.

The address is displayed on the projection screen when a presentation is not in progress. If you're using a security-enabled projector, the projector password is also displayed.

Yes. Any information sent over the connection between your computer and a network projector is protected by Remote Desktop Protocol (RDP) encryption, the same encryption method that Microsoft Windows Server Terminal Services uses.

If you plan to deliver your presentation over a wireless network, you can further protect the information by connecting to a network that uses a wireless security protocol, such as Wi‑Fi Protected Access (WPA) or Wi‑Fi Protected Access version 2 (WPA2).

One or more network-related problems are preventing your computer from connecting to the projector. For example, a router or Domain Name System (DNS) server might be down.

A firewall could be blocking the outbound connection on the projecting machine.
